Williams will also play doubles with sister Venus, the pair teaming up at a Slam for the first time since their 2016 Wimbledon triumph.

Rafa to reign again?

Rafael Nadal confirmed his status as ‘King of Clay’ with his 10th title at Roland Garros last year.

The Spaniard won his 50th consecutive set on clay in Madrid this month, breaking John McEnroe’s record of 49 on carpet in 1984, before going down to Dominic Thiem in straight sets in the quarter-finals.

He then bounced back to triumph in the Rome Masters, losing two sets in the process.

Nadal was similarly dominant last year and won the French Open without dropping a set.

With Roger Federer again absent and Stan Wawrinka and Novak Djokovic on the comeback trail, there are seemingly few challengers to Nadal’s throne.

Thiem and Madrid victor Alexander Zverev would appear to be his biggest rivals, but few would bet against Nadal completing ‘The Undecima’.

Elina’s history bid

Ukraine’s only Grand Slam success came in 2008 when sisters Alona and Kateryna Bondarenko took the Australian Open doubles.
